Ancient Fiend Dragon Emperor

Although the Destruction Empress’s words were harsh, they were indeed truthful.

The Phoenix Sect can’t stay holed up within the Xumi Ring of the Holy Son forever.

Previously, Lian Yuze had mentioned to Su Han that some disciples of the Phoenix Sect wished to go out and experience the world, but Su Han did not agree.

But now...

Thinking it through carefully, the comprehensive battle power of the Phoenix Sect has already greatly increased.

Moreover, considering the forces of the Three Teachings, Nine Schools, and Seventy-Two Sects, Sub-Immortal Level experts have long gone into hiding, and Heavenly Emperor Realm experts rarely appear. They probably wouldn’t target ordinary disciples of the Phoenix Sect, as that would be shameful.

If they really wanted to target someone... it would be Su Han, or even Xuanyuan Qiong and others!

"It’s about time to let them go out and see..." Su Han thought to himself.

However, even if they were to go out, it would have to wait until after he has upgraded the Ultimate Night of the Divine Blade before they could go out completely.

...

In the time that followed, Su Han continued to stay in the valley and began trying to upgrade the grade of the Ultimate Night of the Divine Blade.

To be honest, these Eighth Level Blood Crystals can fuse with artifact refining materials, which was something Su Han did not expect.

This fusion can be said to be extremely simple!

Whether it’s Alchemy or Artifact Refining, many steps are always required. It first refines one type of material and then another.

Until finally, when all these materials are completely refined, the most critical step is then undertaken.

Fusion!

Fusing various artifact refining materials is undeniably the most difficult.

However, these Eighth Level Blood Crystals can indeed fuse...

Directly saving all previous artifact refining steps, one only needs to wait for the fusion to a certain extent, and then infuse all those fused materials onto the Ultimate Night of the Divine Blade’s main body!

In the valley, Su Han sat cross-legged.

On his left side, the Ultimate Night of the Divine Blade was placed.

On his right side, there was a small pile of Blood Crystals.

These Blood Crystals ranged from First Level to Eighth Level, all were present.

"Since Eighth Level Blood Crystals can fuse with artifact refining materials, can First Level Blood Crystals do the same?" Su Han murmured to himself.

Thinking about it, and trying it!

Su Han still had some artifact refining materials.

Before the outbreak of the Extraterritorial Demons, he had killed so many people and destroyed some sects, acquiring not only Spirit Crystals and such.

Weapons are divided into levels, so naturally, artifact refining materials are also ranked, just like medicinal ingredients.

At this moment, the piece of material taken out by Su Han is Spirit-Level material!

Spirit-Level material can be refined into Spiritual Artifacts, which are considered the lowest-grade materials in a Lower-Class Star Region.

Holding the material in his left hand and the First Level Blood Crystal in his right hand.

After observing for a moment, Su Han took a deep breath.

In the next instant—

"Swish!"

The power of cultivation was infused directly, following the operational method of the Divine Fusion Art, acting on the Blood Crystal and artifact refining material.

The situation that followed brought immediate joy to Su Han’s face.

Only to see a blood-red light appear on the Blood Crystal, as if morphing into a large mouth, directly enveloping the Spirit-Level artifact refining material!

After enveloping it, Su Han clearly saw the shape of the artifact refining material manifesting inside the Blood Crystal.

Moreover, under his gaze, the artifact refining material began to... melt!

Yes, melt!

Just like how an Artifact Refiner melts it using furnace fire!

In merely a few seconds, the piece of artifact refining material was completely fused into the Blood Crystal.

Through the Blood Crystal, one could see that the artifact refining material inside had already melted into liquid.

Meanwhile, the Blood Crystal that was only palm-sized grew by approximately one-third.

"It really can fuse!" Su Han’s eyes gleamed.

Following that, he took out a piece of Profound-Level artifact refining material.

However, when he attempted to let the Blood Crystal fuse with this material using the Divine Fusion Art, a crack appeared on the Blood Crystal.

The cracks multiplied, eventually shattering into pieces.

The blood-red color vanished, and even the liquid from the previously fused Spirit-Level artifact refining material solidified immediately.

"Just as expected!"

Su Han did not feel disappointed but instead spoke to himself, "First Level Blood Crystal can only fuse Spirit-Level artifact refining materials; Second Level Blood Crystal can fuse Profound-Level artifact refining materials."

"And artifact refining materials are divided into Spirit-Level, Profound-Level, Ghost-Level, Imperial Rank, Netherworld Level, Ancestor Level, Emperor Level, Sub-Immortal Level—eight tiers, perfectly corresponding to the First Level to Eighth Level Blood Crystals!"

"That means..."

"These Eighth Level Blood Crystals can fuse all artifact refining materials in a Lower-Class Star Region!"

Thinking of this, intense light erupted in Su Han’s eyes.

The current grade of the Ultimate Night of the Divine Blade is only Imperial Artifact, not yet reaching Netherworld Artifact.

If he can procure many high-quality materials, Su Han can infinitely enhance the Ultimate Night of the Divine Blade!

Under the Divine Fusion Art, this enhancement won’t be limited by cultivation base!

Because the reason Artifact Refiners are limited by cultivation base is entirely because of the fusion stage!

Lacking sufficient cultivation base, it’s impossible to perfectly fuse the liquid state of those artifact refining materials, leading to artifact refining failure!

Yet at this moment, with the existence of Eighth Level Blood Crystals, perfect fusion of many materials is possible.

All Su Han needs to do is infuse that fused liquid into the Ultimate Night of the Divine Blade and then wait for its grade to increase!

"It seems..."

Su Han took a deep breath, feeling somewhat excited: "Below Immortal Artifacts, as long as there are materials, I can infinitely enhance the Ultimate Night of the Divine Blade, even up to Sub-Immortal Level!"

However, after searching through his storage ring, Su Han showed a hint of disappointment.

He did have artifact refining materials.

But he truly lacked high-level artifact refining materials.

The highest-level artifact refining materials in his storage ring were merely Netherworld Level.

"I wonder if these Blood Crystals can change in quality due to the abundance of artifact refining materials?" Su Han suddenly pondered this.

Without hesitation, he immediately started trying.

Still using a First Level Blood Crystal, still Spirit-Level artifact refining materials.

But this time, it wasn’t just one piece, but ten pieces!

"Swish!"

Under the circulation of the Divine Fusion Art, the ten pieces of artifact refining materials all transformed into liquid, enveloped by the Blood Crystal.

At that moment, the Blood Crystal grew to the size of a head.

Su Han didn’t pause, continuing to take out more Spirit-Level artifact refining materials.

Twenty pieces, thirty pieces, forty pieces...

Until he reached a hundred and one pieces, after the Blood Crystal had also devoured—

Su Han clearly saw that the liquid inside underwent a quality change, reaching...

Profound-Level!!!

But, just as Su Han began to rejoice, the Blood Crystal cracked once more, shattering again!
